Matthew R. McGuire

Professional Biography

The former Principal Deputy Solicitor General in Virginia’s Office of the Attorney General, Matt is a seasoned appellate and trial court attorney. As counsel, Matt focuses on appellate litigation as well as helping clients frame complex legal issues before trial courts and administrative agencies.

Before joining Hunton Andrews Kurth LLP, Matt served for nearly four years in the Solicitor General’s division of the Office of the Attorney General of Virginia. He represented the Commonwealth, its agencies and its officials in significant and sensitive cases pending before the US Supreme Court, the US Courts of Appeals, the Supreme Court of Virginia and federal and state trial courts. Before the US Supreme Court, Matt briefed, argued and won a 5-4 victory in Currier v. Virginia, 138 S. Ct. 2144 (2018). That case involved a “complicated” constitutional question about the double jeopardy clause, which resulted in one commentator noting “the exceptionally high intellectual plane of the Supreme Court’s discourse” during the argument (SCOTUSBlog 2018). Matt was also the principal attorney defending the sentence imposed on Lee Boyd Malvo, one of the “D.C. Snipers,” including drafting the successful petition for writ of certiorari, granted by the US Supreme Court in 2019. Recently, Matt argued before the full en banc US Court of Appeals for the Fourth Circuit in Manning v. Caldwell, a case challenging the constitutionality of Virginia’s habitual drunkard laws, and successfully represented the Virginia State Bar before the Supreme Court of Virginia in Morrissey v. Virginia State Bar.

Before joining the Attorney General’s office, Matt frequently represented clients before the Federal Energy Regulatory Commission (FERC) in proceedings arising under the Federal Power Act and the Natural Gas Act. Immediately after law school, Matt served as a law clerk for Judge E. Grady Jolly on the US Court of Appeals for the Fifth Circuit.

Matt also co-teaches a course on the Constitution and State Attorneys General at the University of Richmond School of Law.
